Acpi battery script

SoniX · #1 18th January 2007, 04:18 PM

I made myself this battery script:

Code:

#!/bin/sh
# Using the script to change brigtness when going to battery mode
ACAD_BRIGHTNESS=21
BATT_BRIGHTNESS=5
                                                                                                                                
# ac/battery event handler
                                                                                                                                    
status=`awk '/^state: / { print $2 }' /proc/acpi/ac_adapter/ADP1/state`
                                                                                                                                     
case $status in
       "on-line")
               logger "Changing brightness to ACAD level"
	       /usr/bin/smartdimmer --set=$ACAD_BRIGHTNESS 
               exit 0
       ;;
       "off-line")
               logger "Changing brightness to BATT level"
	       /usr/bin/smartdimmer --set=$BATT_BRIGHTNESS
               exit 0
       ;;
esac

Placed it into /etc/acpi/actions and made it executable!

Made myself this conf file

Code:

# Battery configuration
# Written by SoniX

#event=battery.*
#action=/etc/acpi/actions/battery.sh

Placed it into /etc/acpi/events

Reloaded the acpid deamon but this doesn't seem to work... Any idea's?

Found a solution, removed all the previous files, made this script:

Code:

#!/bin/sh
# Using the script to change brigtness when going to battery mode
# Made by SoniX
FILENAME="state"
ACAD_BRIGHTNESS=21
BATT_BRIGHTNESS=5
      
while [ true ]
do                                                                                                             
	# ac/battery event handler                                                                                                                                  
	status=`awk '/^state: / { print $2 }' /proc/acpi/ac_adapter/ADP1/state`
	
	oldstatus=`cat $FILENAME`
                                                                                                                                 
	case $oldstatus in
		$status);;
		*)
			case $status in
			       "on-line")	       						
					/usr/bin/smartdimmer --set=$ACAD_BRIGHTNESS
		 			echo $status > $FILENAME
			       ;;
			       "off-line")
				       /usr/bin/smartdimmer --set=$BATT_BRIGHTNESS
		 			echo $status > $FILENAME
			       ;;
			esac

			echo $status > $FILENAME
			
			sleep 1
			;;
	esac
done

Put it somewhere and make gnome run this script in the background when starting a session

hi SoniX,

i guess you script needs to much cpu time, 'cause of the while true statement - sure you have a sleep call, but it's better to use the event based approach
your config file isn't working because you commented out the interesting stuff
so it should look like:

Code:

# Battery configuration
# Written by SoniX

event=battery.*
action=/etc/acpi/actions/battery.sh

SoniX · #5 19th January 2007, 03:42 PM

STUPID ME!

Now ok, I will chance it to work with acpi, it's indeed much better. But the second script I wrote doesn't take so much cpu power. I don't see a difference, neither with "top" or an applet...

nosnahoj · #6 19th January 2007, 03:52 PM

Why dont you just do two events. One that activates when going from battery to ac (event=ac_adapter) and one from ac to battery (event=battery.*).

SoniX · #7 19th January 2007, 05:13 PM

I don't know why you should need 2 events... Everything works fine now after uncommenting those 2 lines. But I had to add /etc/acpi/actions/battery.sh to the gnome sessions. Otherwise when restarting it won't apply... Now everything works fine

I thought this was a bit simpler:

event=battery.*
action=/usr/bin/smartdimmer --set=5

event=ac_adapter
action=/usr/bin/smartdimmer --set=21

True, but I wan't to add more options, like getting the cpu level down, slowing fans, ... This was just a start :-)

EDIT
I don't think it will work, 'cause the battery event is trigerred when pluging and unpluging the power cable...
